Abstract
In this work, I will be telling you how I derived the E-W line on a small pillar with a flat surface and transferred the same on to the sloped surfaced of my terrace. This was done on April 25th, 2021. And this was verified again on August 18th, 2021. In Bengeluru (latitude of Bengaluru is approximately 130° North), April 25th and August 18th are Zero Shadow Days (ZSDs).
